Speed run of Final Fantasy II in 10 segments completed on April 16 2005. Available in three versions: low quality, normal quality, and 60 fps high quality.
First of all, thanks to Enhasa for outlining a speed run of this game on the SDA message board. Great ideas there, especially the D Machin trick, which I'm convinced is the key to speed running this game. I tried once about a year ago and gave up because my levels were so low when I got to Zeromus.
The only bug I use is the Crystal bug- that is, using Warp to get the Crystal in the Dwarf castle, which then triggers Kain's betrayal as soon as you enter the Sealed Cave.
I made several mistakes, most of which are obvious. The only one I can think of that isn't: I forgot to remove the Flame Armor from Cecil as soon as I should have. Fighting Rubicant with Flame Armor is a bad idea.
I suspect that I gained too many levels at Mount Ordeals and Tower of Zot. Originally, I thought level 27 was pretty conservative for everything before the Elementals. I think lower would have been a little faster, though.
